Remove sealants that fail to adhere to joint substrates during testing or to comply with other requirements. Retest failed applications until test results prove • sealants comply with indicated requirements. • • 3.5 CLEANING • A. Clean off excess sealant or sealant smears adjacent to joints as the Work progresses • by methods and with cleaning materials approved in writing by manufacturers of joint • sealants and of products in which joints occur. • • 3.6 PROTECTION • A. Protect joint sealants during and after curing period from contact with contaminating • substances and from damage resulting from construction operations or other causes • so sealants are without deterioration or damage at time of Substantial Completion. If, despite such protection, damage or deterioration occurs, cut out and remove damaged • or deteriorated joint sealants immediately so installations with repaired areas are • indistinguishable from original work. • • END OF SECTION 07920 • • • • • • • • • • • • • • January 2016 07920-7 6687/Durham O&M Phase 1 b • • • • • SECTION 08111 • • HOLLOW METAL DOORS AND FRAMES • PART 1 - GENERAL • • 1.1 SUMMARY • A.

Contractor shall • remove noncomplying paint materials from Project site, pay for testing, and • repaint surfaces painted with rejected materials. Contractor will be required to remove rejected materials from previously painted surfaces if, on repainting with • complying materials, the two paints are incompatible. • • PART 3 - EXECUTION • • 3.1 EXAMINATION • • January 2016 09912-3 6687/Durham O&M Phase 1 b I I • • • A. Examine substrates and conditions, with Applicator present, for compliance with • requirements for maximum moisture content and other conditions affecting • performance of the Work. • B. Maximum Moisture Content of Substrates: When measured with an electronic • moisture meter as follows: 1. Concrete: 12 percent. • 2. Masonry (Clay and CMU): 12 percent. • 3. Wood: 15 percent. 4. Gypsum Board: 12 percent. • 5. Plaster: 12 percent. • • C. Gypsum Board Substrates: Verify that finishing compound is sanded smooth. • D. Plaster Substrates: Verify that plaster is fully cured. • E. Spray-Textured Ceiling Substrates: Verify that surfaces are dry. • F. Verify suitability of substrates, including surface conditions and compatibility with * existing finishes and primers. • G. Proceed with coating application only after unsatisfactory conditions have been • corrected. • 1. Application of coating indicates acceptance of surfaces and conditions. • • 3.2 PREPARATION • A. Comply with manufacturer's written instructions and recommendations in "MPI Manual" • applicable to substrates indicated. • B. Remove hardware, covers, plates, and similar items already in place that are • removable and are not to be painted. If removal is impractical or impossible because • of size or weight of item, provide surface-applied protection before surface preparation • and painting. 1. After completing painting operations, use workers skilled in the trades involved to • reinstall items that were removed. Remove surface-applied protection if any. • C. Clean substrates of substances that could impair bond of paints, including dust, dirt, oil, • grease, and incompatible paints and encapsulants. • 1. Remove incompatible primers and reprime substrate with compatible primers or • apply tie coat as required to produce paint systems indicated. • • 3.3 APPLICATION 41 A. Apply paints according to manufacturer's written instructions and to recommendations • in "MPI Manual." • • January 2016 09912-4 6687/Durham O&M Phase 1 b • • • • • • 1. Use applicators and techniques suited for paint and substrate indicated. • 2. Paint surfaces behind movable equipment and furniture same as similar exposed surfaces. Before final installation, paint surfaces behind permanently fixed • equipment or furniture with prime coat only. 3. Paint front and backsides of access panels, removable or hinged covers, and • similar hinged items to match exposed surfaces. • 4. Do not paint over labels of independent testing agencies or equipment name, identification, performance rating, or nomenclature plates. • 5. Primers specified in painting schedules may be omitted on items that are factory • primed or factory finished if acceptable to topcoat manufacturers. • B. Tint each undercoat a lighter shade to facilitate identification of each coat if multiple • coats of same material are to be applied. Tint undercoats to match color of topcoat, • but provide sufficient difference in shade of undercoats to distinguish each separate coat. • • C. If undercoats or other conditions show through topcoat, apply additional coats until • cured film has a uniform paint finish, color, and appearance. D. Apply paints to produce surface films without cloudiness, spotting, holidays, laps, brush • marks, roller tracking, runs, sags, ropiness, or other surface imperfections. Cut in sharp lines and color breaks. • • E. Painting Fire Suppression, Plumbing, HVAC, Electrical, Communication, and Electronic Safety and Security Work: • • 1. Paint the following work where exposed in equipment rooms: • a. Equipment, including panelboards. • 2. Paint the following work where exposed in occupied spaces: • • a. Other items as directed by Architect. • 3. Paint portions of internal surfaces of metal ducts, without liner, behind air inlets • and outlets that are visible from occupied spaces. 40 • 3.4 FIELD QUALITY CONTROL • A. Dry Film Thickness Testing: Owner may engage the services of a qualified testing and • inspecting agency to inspect and test paint for dry film thickness. • 1. Contractor shall touch up and restore painted surfaces damaged by testing. 2. If test results show that dry film thickness of applied paint does not comply with • paint manufacturer's written recommendations, Contractor shall pay for testing • and apply additional coats as needed to provide dry film thickness that complies with paint manufacturer's written recommendations. • • 3.5 CLEANING AND PROTECTION • • • January 2016 09912-5 6687/Durham O&M Phase 1 b • • • • • A. At end of each workday, remove rubbish, empty cans, rags, and other discarded • materials from Project site. • • B. After completing paint application, clean spattered surfaces. Remove spattered paints by washing, scraping, or other methods. Do not scratch or damage adjacent finished • surfaces. • C. Protect work of other trades against damage from paint application. Correct damage to • work of other trades by cleaning, repairing, replacing, and refinishing, as approved by • Architect, and leave in an undamaged condition. • D. At completion of construction activities of other trades, touch up and restore damaged • or defaced painted surfaces. • INTERIOR PAINT SYSTEMS: • When additional coats are required, repeat paint type indicated by> symbol in Paint Systems • Schedules. • A.
